• C. Yellow
• D. Green

Answer: (B)

The presence of an underground electrical utility line is typically indicated by the color red. This standard color coding helps to ensure safety and avoid accidental damage during excavation or construction activities. When workers see red markings, they are alerted that there are electrical lines buried below, prompting them to take necessary precautions to prevent utility strikes that could result in power outages or hazardous situations. The other colors mentioned are designated for different types of utilities—blue usually denotes potable water, yellow indicates gas, oil, or steam lines, and green signifies sewage and drain lines. Understanding these color codes is essential for anyone involved in construction, maintenance, or any activities that require digging or excavation, as it helps maintain safety standards and avoid incidents related to underground utility lines.
